Toward Live Language Development

We would like to see live programming applied to language development, to getlive language development. With live language development, a language developer gets fast feed- back when they change their language, enabling experimentation with language design and development. In this paper, we describe what live language development is and why it is useful, and we analyze what is needed to achieve live language development. Moreover, we describe our work in progress in supporting live language development in the Spoofax language workbench.
